Looking Back at Fifty Years of the Clean Air Act

Looking Back at Fifty Years of the Clean Air Act. Joseph Aldy, January 2020, Paper, “Since 1970, transportation, power generation, and manufacturing have dramatically transformed as air pollutant emissions have fallen significantly. To evaluate the causal impacts of the Clean Air Act on these changes, we synthesize and review retrospective analyses of air quality regulations. The geographic heterogeneity in regulatory stringency common to many regulations has important implications for emissions, public health, compliance costs, and employment. Cap-and-trade programs have delivered greater emission reductions at lower cost than conventional regulatory mandates, but policy practice has fallen short of the cost-effective ideal. Implementing regulations in imperfectly competitive markets have also influenced the Clean Air Act’s benefits and costs.Link

Carbon Tax Review and Updating: Institutionalizing an Act-Learn-Act Approach to U.S. Climate Policy

Carbon Tax Review and Updating: Institutionalizing an Act-Learn-Act Approach to U.S. Climate Policy. Joseph Aldy, 2019, Paper, “The design of climate change policy faces the challenge of several key uncertainties. First, the potential benefits of reducing carbon dioxide (CO2) and other greenhouse gas (GHG) emissions are characterized by an array of uncertainties related to long-term economic growth, climate sensitivity, the effectiveness of emissions mitigation policy, and the climate risk mitigation actions undertaken through adaptation and geoengineering (Interagency Working Group on the Social Cost of Carbon 2010; Greenstone, Kopits, and Wolverton 2013; Aldy 2015; Taylor 2015). Second, the potential costs of reducing emissions are characterized by uncertainties about the relative costs of low-carbon and carbon-intensive energy sources, technological innovation, consumer responsiveness to energy price changes, as well as the cost-effectiveness of policy design (Aldy et al. 2010). Third, the distributional consequences of climate change and climate policy responses are also characterized by uncertainty (Burtraw, Sweeney, and Walls 2009; Metcalf 2009; Rausch et al 2011; Carleton et al. 2018). Finally, the competitiveness impacts of emissions mitigation policy are uncertain and may vary with the relative stringency of policies around the world, transportation costs, and the energy intensity of manufacturing (Ederington, Levinson, and Minier 2005; Aldyand Pizer 2015; Aldy2017b).Link

Birds of a Feather: Estimating the Value of Statistical Life from Dual-Earner Families

Birds of a Feather: Estimating the Value of Statistical Life from Dual-Earner Families. Joseph Aldy, March 2019, Paper, “Economists have long employed hedonic wage analysis to estimate income-fatality risk trade-offs, but some scholars have raised concerns about systematic measurement error and omitted variable bias in the empirical applications of this model. Recent studies have employed panel methods to remove time-invariant individual-specific characteristics that could induce bias in estimation. In an analogous manner, this paper proposes to exploit assortative matching on risk attitudes within married couples to control for worker characteristics that are unobserved to the econometrician. I develop and implement a modified hedonic wage estimator based on a within-coupled differenced wage equation for full-time working married couples with the Current Population Survey Merged Outgoing Rotation Group over 1996-2002. The key assumption builds on the findings in the assortative matching literature that individuals often marry those who have common traits across many dimensions, including those that may influence worker wages and are correlated with observed occupational fatality risks.Link

What Green New Deal advocates can learn from the 2009 economic stimulus act

What Green New Deal advocates can learn from the 2009 economic stimulus act. Joseph Aldy, February 15, 2019, Opinion, “Congressional Democrats have introduced a “Green New Deal” proposal that calls for a 10-year national mobilization to curb climate change by shifting the U.S. economy away from fossil fuels. Many progressives support this idea, while skeptics argue that a decade is not long enough to remake our nation’s energy system.Link

The Economic Implications of a Low-Carbon Future

The Economic Implications of a Low-Carbon Future. Joseph Aldy, January 2019, Paper, “What are the costs and benefits of reducing the carbon intensity of the U.S. economy? The economic costs of decarbonization reflect the stringency of climate policy goals—how ambitious is the objective and how quickly must the economy meet it—and the responsiveness of investment and consumption to new policies and associated price signals. The more low-cost opportunities for switching to lower- and zero-carbon energy sources and the more options for energy efficiency and conservation, the lower the cost of any decarbonization goal. The costs will also reflect a number of critical policy design choices that will affect the cost-effectiveness of reducing carbon emissions, the creation and use of economic value (such as carbon tax revenues) that could promote economic growth, and the potential for innovation policy to complement emission mitigation policy.Link

Evaluating the performance of regulations and regulatory institutions

Evaluating the performance of regulations and regulatory institutions. Joseph Aldy, 2018, Book Chapter, “If markets function well in allocating resources, then government regulation is unnecessary. Indeed, government intervention in well-functioning markets will likely  make society worse off by imposing costs that exceed their benefits. If markets do not…Link

Trade Shifts Pollution More than Regs Shift Trade

Trade Shifts Pollution More than Regs Shift Trade. Joseph Aldy, September/October 2018, Paper, “Burning coal to power manufacturing
contributes to premature mortality in the United States and in developing countries alike. Despite stringent environmental regulations, U.S. coal-fired power plants still cause tens of thousands of early deaths each year. Any factor that causes manufacturing activity to shift from the United States to other countries can also shift the demand for coal-fired power — and its pollution — to these other countries.Link

Learning from Nationally Determined Contributions

Learning from Nationally Determined Contributions. Joseph Aldy, April 2018, Paper, “National governments have submitted emissions mitigation pledges under the Paris Agreement that vary considerably in form, level of required emissions mitigation, elaboration of nonemissions goals, and implementation strategies. As a result, domestic emissions mitigation programs necessary to deliver on the Paris pledges will diverge in the degree to which that mitigation will be achieved at least cost. This paper explores both what we learn from how nationally determined contributions (NDCs) diverge from least-cost policies and the implications for comparing mitigation efforts.Link
